After a friend of mine pointed out a bicycle trail he had recently mapped in Milpitas, I checked it out, and I noticed a few problems in the area that I decided to clean up:

* Connected up the trail to the adjacent street.
* Moved a few nearby streets with incorrect TIGER data.
* Added a couple of missing streams based on the satellite images
* Marked a few bridges over these streams.

This area doesn't look like its had much detailed attention yet. My cleanups were relatively limited in scope. Someone could probably spend an afternoon or two just finishing up the tasks I started here.

The Pacific Coast Bike Route is a very popular bicycle touring route that follows the Pacific Coast of the United States from approximately Vancouver, British Columbia to Tijuana, Mexico. Caltrans District 1 still maintains and publishes maps for the portion of the route from the Oregon border through Del Norte, Humboldt, and Mendocino County. After getting explicit permission from Caltrans District 1, I have added a portion of the Pacific Coast Bike Route as a regional cycle network route in OSM.

As far as I know, only Oregon and Caltrans District 1 still publish official maps of the Pacific Coast Bike Route. I am still seeking permission from Oregon to use their map to add the Oregon section to OSM. The very nice folks at Caltrans District 1 are currently checking to see if any of the other Caltrans districts still publish maps of the route.

Variations on the Pacific Coast Bike Route are also published by the Adventure Cycling Association and in the book Bicycling the Pacific Coast. Both of these routes diviate to some extent from the official route.

In additional the Pacific Coast is one of the corridors in the proposed official US National Bike Route Network that was recently approved by the AASHTO, so this route may eventually be upgraded from a regional route to a national route.

Score! I ran across another small municipal airport that had not been mapped, a few miles south of Fortuna, CA. This is apparently the Rohnerville Airport.

There is apparently a convention of labeling these small general aviation airports as aeroway=aerodrome, and reserving aeroway=airport for larger airports that handle commercial passenger aviation. I have also updated the Healdsburg Municipal Airport to follow this convention.

I noticed that the names of the primary cities on the ABC islands seemed a little out of proportion, so I updated their place designations to be more in line with their actual sizes. Kralendijk is not a 100,000 person city! :)

I also tagged Sorobon Beach and the Sorobon Beach Resort. The latter I added with tourism=resort. I'd be happy to change it if there is a more appropriate tag or value. This is a small, clothing optional resort, which rents cabins for extended stays, has day visitors, and has a bar, restaurant, beach, and a few other amenties.

I was looking at the map near Arcata, CA, and I noticed that the satellite imagery had what appeared to be a bike bridge connecting was an otherwise dead end road to a other road on the other side of a river. Oddly enough, Google Street View had taken photographs all the way out to the end of the dead end, and the Street View photographs confirmed that this is in fact a bicycle bridge.

Since the Gravitystorm Cycle Map does not render ways tagged as highway=path, I have retagged a couple of ways that I had previously marked as highway=path. Both were simple dirt trails that apparently developed though simple usage.

One of the trails is a short-cut that links the Guadalupe River Trail to Component Drive, and from there to the Component VTA light rail station. I have since learned that this trial lies on a right of way the the City of San Jose either owns, or has easement rights to, and they have proposed to develop this corridor into a multi-use path: http://www.sjparks.org/Trails/ComponentTrail.htm. Therefore, I have retagged this trail as highway=cycleway.

The other trail is a bit murkier. I have no idea of its official status, but it leaves the eastern lobe of the Silver Creek Linear Park through a 20' hole in its southern fence, and then traverses property whose ownership I don't know to small clearing next to the creek. I retagged this one as highway=footway, since I suspect that this is how this trail is actually used.

Finally, I did some more clean up of the TIGER data in the Silver Creek neighborhood. Some have suggested that any way that has ever been edited should automatically have its tiger:review=no tag effectively cleared. But given my clean-up style, I think this would be a bad idea. When I'm cleaning up an area, I will often only clean up *part* of a way, not the entire way, since cleaning up a entire way may necessitate cleaning up a whole other chunk of map that I'm not ready to tackle yet.

The OSM wiki seems to indicate that no one has yet come up with a good scheme for adding stop signs to OSM. There is an existing highway=stop tag that can be applied to nodes, but it provides no way to specify which ways connected to that node actually have a stop sign.

So, I suggested a new mechanism for tagging stop signs using relations that should be flexible enough to handle any kind of situation involving stop signs that I've been able to think of. I have submitted a formal proposal yet, but I did add a description to the highway=stop discussion page.

In the meantime, I tried out the new scheme by tagging all the stop signs on my bike route to work along S 7th St., N 7th St. and N. 4th St. near downtown San Jose.

This route doesn't have anything too exotic, but it does have a few things beyond the garden variety four way stop.

This tagging scheme does generate a *lot* of relations, and road with a lot of stop signs will have a lot of relations following this tagging scheme.

If anyone is curious to see what I did, you can examine the map area indicated in this diary entry.

As I was cleaning up the rural roads around Healdsburg, I ran across an airport that hadn't been mapped yet. It was quite a treat to be able to add a major feature like an airport, even if it was only a local general aviation airport.

Several weeks ago, some friends and I went riding in Healdsburg, CA and the surrounding area up in Sonoma County. As always, I collected GPS tracklogs.

This morning, I finally got around to uploading the tracklog, and before I even started using the tracklog, I noticed that appeared that nobody had even begun to clean up the TIGER import at all in downtown Healdsburg, so I have mostly been cleaning up the streets against the Yahoo aerial maps.

Someone will really need to go collect some data on the ground in Healdsburg, because there are quite a few places in the Tiger data that just don't make sense based on the aerial photography: streets that don't seem to exist, streets that don't connect but appear that they should, streets that do connect but appear that they shouldn't, and so on.

I did the best I could, with what I could be reasonably sure of based on the aerial photography. Unfortunately, my GPS tracklogs were primarily in the rural areas surrounding Healdsburg, so they weren't particularly useful for cleaning up downtown Healdsburg.

I have added place=hamlet nodes in several local neighborhoods that I frequent, including Spartan-Keyes, Willow Glen, and Silver Creek

Added a few updates to my home town, including marking a few schools and one of the major landmarks, the Astor Column

Today, for the first time, I noticed there is an actual creek in the Silver Creek area. It is completely missing from the map, but its location is obvious from the riparian zone surrounding it, so I have started to map it out.

This morning I went on a mapping ride in the Silver Creek area of San Jose. I traced out the Upper Silver Creek Trail, noted the location of a few bike lanes and bike routes, noted the location of the Hellyer Velodrome, and added a bunch more details, street names, and so on, in the new development on the hill between Coyote Creek and Silver Creek.

I added some more minor corrections and additions to Bonaire:

* Fixed up some of the streets along the waterfront north of Kralendijk.
* Fixed a couple of features that were misidentified as streets instead of piers
* Added a name for Town Pier
* Marked a few of the BNMP numbered dive sites that I dove on my last visit, using the sport=diving proposed tag.

I visited Bonaire island in the Caribbean this summer, and shortly after I returned I decided to transcribe what I rememebered into OpenStreetMap. By the time I visited, most of the island had been traced in, apparently from satellite imagery only, since important details like street names and one-way restrictions were missing. In a few instances where I recalled such details, I added them to the map.

This morning, I went back to check on Bonaire again. Not much seems to have changed, but while I was there, I added points and labels for a few important features, including Lac Bay, Lake Gotomeer, and Washinton-Slagbaai National Park. Perhaps I or someone else will trace in the precise boundaries of these features in the future.

Since Bonaire is world famous as a Scuba destination, I was hoping that someone would add in the locations and names of the official entry points of the National Marine Park by now.

Completed the southern portion of the Highway 87 Bikeway, using the aerial photography as a guide. Tagged both the offstreet and on-street alignments with a route relation labeled Highway 87 Bikeway.

The area between 16th and 17th and San Salvador and San Fernando has a lot of interesting traffic diverters, and I did my best to add these in using the restriction relation.

I also added a random smattering of amenities, and traffic calming measures.

On N. 10th St just south of Commercial St., the signed and painted bike lane explicitly and inexplicably turns into a signed Class III Bike Route for 240' and then turns back into a Bike Lane. This is very weird, but I updated the map to reflect observed reality.

I've begun to document traffic calming measures on the streets I ride on regularly, including chokers, speed humps, and mini-roundabouts.

I recently added an informal dirt trail that links the Guadlupe River Trail to Component Drive and the Karina VTA light rail station. this short-cut through an open field shaves nearly a mile off the current official route that goes all the way to Trimble.

Thanks to adbrown who pointed out that this trail is actually the proposed future Component Trail: http://www.sjparks.org/Trails/ComponentTrail.htm

It is noteworthy that the current path as it exists has a very steep slope at the junction with the Guadalupe River Trail, but I'm not sure how to tag this.

I recently cycled the San Jose Crosstown Bikeway Route 11 from its northern terminus to as far south as Monterey Highway at Metcalf and added this as an LCN route. The route continues further south, but I didn't have the time nor stamina to get it all in one go. I haven't been able to find any kind of online description of Route 11, so either I or someone else will have to continue surveying on Monterey Highway from Metcalf to the southern terminus of the route.

I added the two northernmost sections of the Highway 87 Bikeway by tracing them from the aerial photograph. The southernmost section is too hard to distinguish on the photograph, so I may have to collect a GPS trace for this section.

I have recently added bike lane designations for areas that I ride on a regular basis, including in downtown, and in the vicinity of the Airport.

I've traced in a number of large and/or notable buildings, including eBay's North campus, the Walmart on Story Rd., and Bay 101.

I have also been adding amenities that I know of, such as bike shops, motels, post offices, post boxes, and water fountains.
